Abstract
Fluorescent magenta latexes are provided which may comprise water and fluorescent agent-incorporated resin particles, the particles comprising a resin, Solvent Red 49 as a red fluorescent agent, and Solvent Yellow 98 as a yellow fluorescent agent, wherein the fluorescent magenta latex has a weight ratio of the Solvent Red 49 to the Solvent Yellow 98 in a range of from 3:1 to 10:1. Fluorescent magenta toners and methods of making and using the fluorescent magenta toners are also provided.
Claims14
A fluorescent magenta latex comprising water and fluorescent agent-incorporated resin particles, the particles comprising a resin, Solvent Red 49 as a red fluorescent agent, Solvent Yellow 98 as a yellow fluorescent agent, and a fluorescent brightener having a fluorescence emission spectrum that overlaps with an absorption spectrum of the yellow fluorescent agent, wherein the fluorescent magenta latex has a weight ratio of the Solvent Red 49 to the Solvent Yellow 98 in a range of from 3:1 to 10:1, and wherein the fluorescent magenta latex exhibits Förster Resonance Energy Transfer (FRET) under illumination with light having a wavelength to excite the yellow fluorescent agent and FRET under illumination with ultraviolet light.
